Full-Scaled Experiment for Behavior Investigation of Reinforced Concrete Columns with High-Strength Wire Ropes as Lateral Spiral Reinforcement

Abstract

AbstractThis study performs the test with full-scaled models for each diameter to evaluate the behavior of the reinforced concrete columns using the spiral wire rope as a lateral reinforcement of the circular columns. This study performs the quasi-static test which induced binding shear destruction to review circular concrete columns bound with high strength wire rope. Three specimens of concrete columns with 700 and 800 mm diameter each were manufactured to evaluate the movement of reinforced circular columns with the wire rope. A hoop reinforced column and 2 spiral reinforced columns were manufactured to compare the bending history and the ductility reinforced with the wire rope to existing reinforced concrete columns. The peak strain of the longitudinal reinforcements is occurred at approximately 0.75 D from the bottom of the column. The spirally confined concrete columns with high-strength wire ropes showed that improve 2.5 % of the shear strength.KeywordsWire ropesSpiralDuctilityColumnsLateral reinforcements
